Magnetometer by Marine Magnetic's

Marine Magnetic's takes pride in designing and manufacturing magnetic exploration equipment that meets scientific observatory specifications. The Sea SPY magnetometer product eliminates many of the inherent problems associated with other marine magnetometers such as orientation restrictions, sensor realignment,time and temperature drift and poor absolute accuracy.

The Overhauser Effect

Marine Magnetic's is the only marine magnetometer company in the world that can produce stable Overhauser sensors that do not degrade with time. Marine Magnetic's ? Sea SPY magnetometer measures the ambient magnetic field using a specialized branch of nuclear Magnetic Resonance technology, applied specifically to hydrogen nuclei.

Worldwide Operation With No Restrictions

The Sea SPY sensor is unique in that it is entirely omni directional. The amount of signal produced by the sensor is completely independent of magnetic field direction. You have to orient your sensor, because it is already optimized to work around the World. As a result, regardless of where you are in the World and no matter what the magnetic field strength is, your Sea SPY sensor will continue to provide a strong signal and accurate data.

Digital System

Sea SPY is entirely digital. The magnetometer signal is measured inside the tow fish where the signal is strongest and most immune to outside noise.

No Sensor Warm-Up Time

Sea SPY Overhauser sensors do not require temperature stabilization. Therefore, unlike competing technologies, Sea SPY will work equally as well in cold, deep water as in warm, tropical water, instantly on power-up.

Highest Absolute Accuracy

Sea SPY Overhauser sensors have the highest absolute accuracy of any magnetometer: 0.2nT The repeatability between Sea SPY sensors is also unmatched at better than 0.01nT. This makes them ideal for gradiometer configurations, where the output of two independent sensors is compared to measure the value of magnetic gradient between them.

High Sensitivity

Sea SPY Overhauser sensors deliver high-resolution output with a noise level of 0.01nT/Èz; counter sensitivity is 0.001nT

Maintenance Free Sensors,

No Realignment and No Consumable Parts Sea SPY Overhauser sensors are entirely maintenance free and most importantly, Sea SPY's specifications do not degrade over time. As a result, the Sea SPY sensor never has to be realigned, or recalibrated in order to meet the manufacturers specifications at the time of shipping. In addition, the Sea SPY sensor does not contain any parts that wear out and need to be replaced.

Ultra Low Power Consumption

A Sea SPY system only requires 1W standby and 3W maximum. Sea SPY can run for days directly from a 24V vehicle battery.
